摘要
reactivity of 6-haloimidazo[1,2-alpha]pyridine toward different azoles is reported. The process was shown to be highly dependent on the reaction conditions. Using copper(l) catalyst, the product of ;ipso substitution was obtained. In the absence of copper, with cesium carbonate in N,N-dimethylformamide, a cine substitution took place.
